Abstract

The model is done in Solid Works as per the standards. Solid model is then imported to ANSYS workbench environment so as to perform thermal and static structural analysis. In thermal analysis, the model is given heat flux, convective heat transfer and ambient gas temperature and then is solved for temperature distribution over the blade.

The obtained temperature distribution is taken as the thermal load into the static structural analysis. In static structural analysis, the model is given BCs and structural loads viz; centrifugal force, tangential force and pressure. The model is then solved for stresses and deflections. The von-Misses stress and Total deformation plots are taken for various operating conditions i.e., temperatures and speeds. The results are then compared for variable gas temperatures and turbine speeds.
